This is Why You Don't Eat Three Boxes of Fiber One Bars

Some people need a little extra fiber in their diets, but there’s definitely such a thing as too much of it. So if someone were to eat nothing by Fiber One bars for two days, it’s pretty much assured their digestive system will not take it well. One Reddit user posted in r/TIFU (which stands for Today I Fucked Up) about his adventure with this nutritional snack.

Why did he have three boxes of Fiber One bars just lying around in the first place? Does his digestive really need that much encouragement?
